Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed November21, 1917. Serial No. 203,124.

To all whom it may concern:

Be it known that I, HUMBnR'ro MACERA, citizen of Argentine Republic, residing at No. 766 Piedras street, Buenos Aires, Argentina, have invented certain new and useful Improvements in Protective Coverings for Envelops for Containers of Glass and the like, of which the following is a specification.

This invention relates to an improved protective and insulating covering or lining for glass. containers or vessels and the like. The principal object of the invention is to provide an inexpensive and flexible covering, particularly adapted for protecting the container against injury, temperature changes, and the action of light. Other objects will be in part obvious and in part pointed out hereinafter.

In the accompanying drawings in which is illustrated one of various possible embodiments of this invention,

The figure illustrates. a central vertical section of a carboy provided with a protective covering.

According to the illustrated embodiment of the invention, a vessel or container of glass or similar material is provided with an envelop or lining of material such as corrugated cardboard, fitted against the surface of the container and covered with a coating of fibrous paste which hardens and forms an integral part of the entire covermg.

In the accompanying drawing, a container a, in this instance a carboy, is shown as covered with corrugated cardboard b, andon this cardboard is applied a covering or coating a of fibrous material, which affixes itself to the cardboard, the whole forming an inte ral article.

With this construction, the container is eificiently protected against mechanical injury and atmospheric influences, and its. contents are protected against the action of light. Furthermore, the cover acts as a heat-insulating medium, and thus assists in maintaining the temperature of the contents constant, despite changes in the temperature of the surrounding atmosphere.

My invention is obviously not limited to the embodiment illustrated in the accompanying drawings.

I claim:

1. An insulating and protective envelop or covering for containers comprising an inner lining of heat-insulating material and a layer or coating of fibrous paste applied to the inner material.

2. A protective envelop or covering for containers comprising a layer or coating of fibrous paste molded upon the container and provided on its inner surface with corrugations.

3. A container having a resilient material applied to its outer surface and a plastic material molded around said resilient material.

4. The method of applying a protective covering to a container which comprises applying a resilient material to the outer surface of the container, and applying a plastic material around said resilient material.

5. The method of applying a protective covering to a container which comprises applying corrugated cardboard to the outside of the container and securing the cardboard in position by applying a fibrous paste thereto the paste becoming hard upon drying.

In testimony whereof I aifix my signature in the presence of two witnesses.
